This paradisiacal place is home to an infinite number of organisms that have adapted to living in the vast expanses of sandy bottoms or in the vibrant reefs that grow on its margins.

Behind the colossal barriers of Kýanos Metrópoli stretches the immense lagoon of Mare Seppi. Its shallow basin covers an area as large as all of Eurasia.

Protected from strong ocean currents, this shallow, warm and illuminated paradise is home to a great diversity of creatures.

A clear example of Williston's law can be seen in the phylum Pharyngopoda. Primitive groups(left), have a huge number of identical and unspecialized zooids in their colonies, while in derived groups(right) the number is reduced but their specialization increases.

Stratozoa is one of the most diverse phylums of polizoans. Its name literally means "layered animals" and refers to the curious growth method of its colonies. Each of its digestive zooids develops a "son zooid" that grows within its own gastric cavity and emerges through its (+)

Mediophthalmus, a meter-long predatory amphimorph. Their siphons are equipped with an organ similar to a retractable beak, with which they tear their prey. The mouth is located in the center of the body and diverges into two independent digestive tracts located on each side.

Laimargia is one of the most characteristic and recognizable organisms in the Polinices reefs. This basal pharyngopod has developed detritivorous habits, so its zooids are adapted to engulf sand and digest the organic matter found in it, something they achieve thanks to their (+)

Coasts of Zelia, the arid and hostile supercontinent of Polinices. On the shores of the global ocean, ancient fossilized hive sponge reefs are eroded by the action of waves and wind, creating immense columnar structures.

Gyromonilea is a class of radioscriptorans related to the hive sponges. Sessile queens spawn swimming drones, which group together to form a rotating circular ribbon, each drone depositing the trapped plankton during the spin on the queen. The queens can be solitary or colonial

Carboniferous period, southern Gondwana. A stream of freezing water has formed a rocky valley that runs through the lycophytes forest.
The second image shows a river inhabitant, Euproops (a freshwater horseshoe crab), which digs the clayey bed in search of organic matter to eat.
